ZooKeeper support ends with Apache Kafka 4.0, forcing teams to migrate to KRaft-based clusters. Confluent introduces KCP (Kafka Copy Paste), an open source tool that simplifies migration planning from hosted Kafka to Confluent Cloud in minutes. The tool uses Cluster Linking to mirror topics byte-for-byte while maintaining consumer offsets. Confluent Cloud offers 40-70% cost savings through serverless autoscaling, Private Network Interface for reduced networking costs, and Freight clusters for high-throughput workloads. The platform provides 99.99% uptime SLA, multicloud support, 120+ connectors, integrated governance, serverless Flink, and Tableflow for zero-ETL analytics.
